When he was discharged he was presented with a wrestling belt which was paid for by the Children’s Hospital Charity.

“It was frustrating,” said Kane.

“My hips and thighs really hurt so I couldn’t play or go on my bike.”

Robert, Kane’s dad, said: “It was gutting for him, and horrible for us to see him unable to run around, but the care he’s had has been brilliant.

“He’s getting better walking, and he’s got his confidence back. “It feels like things are getting back to normal.”

Dr Dan Hawley, who is a consultant paediatric rheumatologist at Sheffield Children’s Hospital, said: “The aim of our medical treatment is to reduce the amount of time that the inflammation is active and although we can’t cure the condition, we have much better treatments nowadays.

“We aim for patients to lead as normal a life as possible.”

Kane’s physiotherapist Oliver Ward said: “We are very pleased with how well Kane has done following his admission to hospital earlier on this year.

He added: “His love for wrestling and football were integrated within his daily rehabilitation schedule and so The Children’s Hospital Charity funded the wrestling belt which we gave to him when he was discharged.”
